Problem with GPT Bios Partition

[Denny Bortfeldt]

Hello everyone,

just a follow-up. With the help from Kerim I could managed my setup.
The disk-label "gpt-bios" will create this special 2MB Bios-Partition at
the end of the part-layout. It's not neccessary to define it in the
disk_config-File.

So to create my layout as I mention in the first mail my disk_config looks
like this now:


# <type> <mountpoint> <size>   <fs type> <mount options> <misc options>

disk_config disk1 disklabel:gpt-bios bootable:3 fstabkey:uuid

primary swap 8192 swap rw
primary /boot 512 ext4 rw,noatime,errors=remount-ro
primary / 15360 ext4 rw,noatime,errors=remount-ro




Thanks everyone for helping me out!


Best regards,
Denny
